Installing the Dynamic Workload Console servers

Procedure for installing two Dynamic Workload Console servers on two separate nodes.

This picture describes the steps required for installing the master domain manager. You are now at step 6: installing the Dynamic Workload Console

Procedure for installing the Dynamic Workload Console

In this scenario, the IBM® Workload Scheduler administrator installs two Dynamic Workload Console instances on two separate workstations, sharing the same remote database. The IBM Workload Scheduler administrator performs the operations listed below on both workstations.

Certificates are now required when installing or upgrading IBM Workload Scheduler. You can no longer install nor upgrade IBM Workload Scheduler without securing your environment with certificates. The required certificates are:

ca.crt
tls.key
tls.crt

For UNIX systems, ensure that all the files have the ownership of the user who installed the master domain manager and the correct permissions (644).

Note: If you use Db2 for z/OS with Dynamic Workload Console version 10.2.4 or later, transfer the drivers in binary mode from your Db2 for z/OS installation to a directory of your choice. Specify this directory using the dbdriverspath parameter when running the configuredb or dwcinst scripts.

Note: If you are installing the Dynamic Workload Console version 10.2.3 or later, the Federator is also automatically installed. This component enables you to monitor your objects through the Orchestration Monitor page of the Dynamic Workload Console. For detailed information about how to configure and use the Federator, see Mirroring the z/OS current plan to enable the Orchestration Monitor.

If you are installing the on a z/OS operating system, see Installing a Dynamic Workload Console server.

The IBM Workload Scheduler administrator installs the Dynamic Workload Console. The following information is required:

Table 1. Required information
Command parameter	Required information	Provided in..
Database information
--rdbmstype	database type	Creating and populating the database
--dbhostname	database hostname
--dbport	database port
--dbname	database name
--dbuser	database user name
--dbpassword	database password
Security information
--sslkeysfolder	name and path of the folder containing certificates	Installing the master domain manager and backup master domain manager
--sslpassword	password for the certificates	Installing the master domain manager and backup master domain manager
WebSphere Application Server Liberty Base information
--wlpdir	WebSphere Application Server Liberty Base installation directory	Installing WebSphere Application Server Liberty Base

You can run the dwcinst command specifying a typical set of parameters. In this case, default values are used for all remaining parameters.

Default values are stored in the dwcinst.properties file, located in the root directory of the installation image.

If you need to modify any of the default values, edit the dwcinst.properties file, but do not modify the dwcinst.template file located in the same path.

You can specify values in the properties file, type them in the command line, or use both methods. If a parameter is specified both in the properties file and in the command line, the command line value takes precedence.

Before starting the Dynamic Workload Console installation, ensure the following steps have been completed:

Installing WebSphere Application Server Liberty Base on the workstations where you plan to install the Dynamic Workload Console
Creating and populating the database
Creating the IBM Workload Scheduler administrative user
On UNIX™ operating systems, ensure that umask is set to 022. To verify that umask is set to the correct value, from a command prompt, run the umask command. If the value is different from 022, modify it by running the following command:
```
umask 022
```

Note:

Ensure that the inst_dir parameter is different from the directory of the installation image and it does not contain any IBM Workload Scheduler instance.
Recent JVMs do not fully support use of non-ASCII characters with the -jar and -javaagent commands. Use only ASCII characters in your installation directory names and paths.

To install the Dynamic Workload Console, perform the following steps:

Log in to the workstation where you plan to install the Dynamic Workload Console.
Download the installation images from IBM Fix Central.
Browse to the folder where the dwcinst command is located in image_location/TWS/interp_name.
Start the installation specifying a typical set of parameters:
On Windows operating systems
```
cscript dwcinst.vbs --acceptlicense yes --rdbmstype db_type
--user dwc_admin_user --password dwc_pwd --dbname db_name
--dbuser db_user --dbpassword db_pwd --dbhostname db_hostname
--dbport db_port --wlpdir Liberty_installation_dir\wlp
--sslkeysfolder certificate_files_path --sslpassword keystore_truststore_password
```
On UNIX operating systems
```
./dwcinst.sh --acceptlicense yes --rdbmstype db_type
--user dwc_admin_user --password dwc_pwd --dbname db_name
--dbuser db_user --dbpassword db_pwd --dbhostname db_hostname
--dbport db_port --wlpdir Liberty_installation_dir/wlp
--sslkeysfolder certificate_files_path --sslpassword keystore_truststore_password
```
where,

user dwc_admin_user

is the administrator of the Dynamic Workload Console. This user is added to the group of the Dynamic Workload Console administrators at installation time. You can use this account to log in to the Dynamic Workload Console and manage your environment.

password dwc_pwd

is the password of the Dynamic Workload Console user.

On Windows operating systems

Supported characters for the password are alphanumeric, dash (-), underscore (_) characters, and ()|?*~+.@!^

On UNIX operating systems

Supported characters for the password are any alphanumeric, dash (-), underscore (_) characters, and ()|?=*~+.

You have now successfully installed the Dynamic Workload Console.

Important: To ensure compatibility, the Dynamic Workload Console version installed must always be equal to or greater than the version of any engine it connects to.

For more information about all dwcinst parameters and default values, see Dynamic Workload Console installation - dwcinst script.

You can now proceed to Installing agents.
